3. Severe uterine fibroids not only cause heavy menstrual flow, but also symptoms of frequent menstruation or shortened menstrual cycles.

6. Dysfunctional uterine bleeding in adolescence: The reason why adolescent women have short menstrual cycles is often due to the incomplete development of the hypothalamus, pituitary gland, and ovarian functions.

Answer 2:

(1): The reasons for short menstrual cycle may be caused by organic diseases or drugs, including local inflammation, tumors and developmental abnormalities of the reproductive organs, malnutrition; intracranial diseases; other endocrine dysfunctions such as thyroid and adrenal cortex dysfunction, diabetes, Sheehan's disease, etc.; liver diseases; blood diseases, etc. Menstrual irregularities may occur in women who use drugs to treat mental illnesses, endocrine preparations, or intrauterine devices for contraception. Certain occupations, such as long-distance runners, are prone to amenorrhea. In addition, some abnormal bleeding during pregnancy is often mistaken for menstrual irregularities.

I believe that after a period of conditioning and treatment, your short menstruation will improve as soon as possible.
